Researchers from the institute's Health and Exercise Science Department found that a blend of black pepper, caffeine and capsicum concentrate can burn as many calories as a 20-minute walk.
Assistant professor of exercise physiology Joel Cramer reported that this tri-pepper formula showed energy expenditures of three to six per cent enough to validate weight loss claims.
Peppers are rich sources of vitamins A, C and K and are well-known for their health-boosting properties.
Not only do they add flavour to low-fat diets but they can also prevent cell damage and reduce inflammation.
Separate studies have shown that both hot and sweet peppers can increase body heat and oxygen consumption leading to weight loss by burning extra calories.
Walkers can burn around 100 calories per mile or more depending on speed.
